Upon the end of the shaft at, opposite the pinion 6, a clampingcap 17 issecured. This cap has an internal annular groove 18, and

against the edge of the clamping-flange 21, and they operate to clamp orhold the bindlng material. For this purpose they are recessed, asillustrated, for the purpose of better holding binding material. Theclamping-socket 20 on theside opposite the clampingflange 21 is cutaway, as shown at 23, to

Consequently when the binding material, which is clampedbetween one of the clampingedges 22 and the clamping-flange 21, isbrought around to the knife it is completely severed thereby. Upon theend of the shaft 5, opposite the pinion 13, is secured a knotter. Thisknotter is preferably composed of a stirrup-carrier 25 firmly secured atone end to the shaft 5 and having an annulus 26 at the other end,through which is inserted a sleeve 27 that is secured l he frame 1, andcarries, with a knotter-socket 29, a flange or disk head 30. Upon thetop of the disk head is firmly fixed,preferably by being made integralwith it, a bill 31.

The pro- -jecting end of the pin isscrew-threaded, as 55 illustrated, and carries a nut 35. A spiral spring36 surrounds the pin and is seated at one end-against the end of thesleeve and at the other against the nut 35. This spring tends to holdthe movable bill yieldingly upon top of the fixed bill, the tension withwhich it is held in that position being controllable by means of the nut35.

40 indicates a stud projecting radially from the side of the socket 29and in the path of the projection 37. As the knotter is rotated, theprojection 37 is brought into contact with the stud 40. The movable billis thereupon raised against the tension of the spring 36 and is quicklyrestored to its normal position as soon as the projection 37 is releasedby the stud 10.

The lmotter-socket 29 is provided on one side with a guide-lip 41 forguiding the binding material to the knotter.

The operation of the machine is as follows: Let it be assumed that thecord 4-2 (which termI shall use to designate any preferred form ofbinding material) is set in the machine, as illustrated inFig. 11 of thedrawings, in which the loose end 413 is firmly held in the clamper, thedouble strands, as illustrated at 44:, passing underneath the bill 31.and the other end of the cord 45 communicating in the usual manner wellunderstood in the art with the spool. (Not illustrated.) The loop of thecord represents the manner in which the bundle, which is to be bound, isin practice In this. position, the machine being in operation, the shaft5 rotating in the direc' tion of the arrow in Fig. 1], drives the bill31 under the double strands 414 of the cord and wraps both strandsaround the bill 31 and the movable bill 32, as illustrated in Fig. 12 ofthe drawings. During thefirst quarter-revolib tion of the bill, as willappear by comparison of Figs. 11 and 12, the clamper remains fixed,securely holding the end 43 of the cord, and in the firstquarter-revolution the bill takes up the slack of the cord around thebundle, thereby gathering the bundle closely and firmly and securingsufficient length of cord to partially form theknot. During the rotationof the bill from the end of the first quarterrevolution to thehalf-revolution (compare Figs. 12 and 13) the movable bill 32 is raisedby the stud 40, so that both strands of the cord are during that periodof rotation caught and held between the movable bill 32 an d the bill31. (See Fig. 13.) During the same time the shaft at imparts aquartenrevolution. to the cap 17. (Compare Figs. 12 and 13.) The spoolend of the cord lying in the cut-away part 23 of the socket 20 is bythis movement of the cap 17 caught between the clamping edge 22 and theend of the clamping-flange 21 and is confined and securelyheld betweenthe outer-wall of the clamping-flange 21. and the inner surface of oneofthe segmental flanges of the clamping-cap 1.7, as is clearly At thesame time robut does not completely release, the end 413 of the cord byreason of the movement of the segmental flange opposite the one which isUpon one side the movable bill carries a. projection 37 that moves in abearing 38 in now operated to clamp the needle end of the cord. Thisoperation will be understood by of juxtaposition with saidclamping-flange and thereby release the loose end before the clampingedge 22 carries the needle or spool end of the cord against the knife.By the location of the clamping-flange opposite to the field of rotationof the bill, (illustrated,) the rotation of the cap 17 from thestarting-point (shown in Figs. 11 and 12) to the position shown in Fig.13 and the rotation of the bill materially diminish the distance betweenthe parts which hold the ends of the cord and the bill, (compare Figs.12 and 13,) thus paying out cord to the bill without in any wiseslackening the loop of the spool end of the cord, but utilizingexclusively that portion of the cord properly set apart and appropriatedto the forming of the knot. This may be better understood by observingthat the clamping edges 22 of the cap 17 approach, in passing from theposition shown in Fig. 12 to that shown in Fig. 13, nearer to the bill,while during its rotation from the former to the latter position it isreleasing its hold upon the end 43 of the cord. During that portion ofthe rotation of the cap 17 and of the bill illustrated in Fig. 14 incomparison with Fig. 13, the cord is first forced snugly in placebetween the bills 31 and 32. Then the end 43 of the cord is e11- tirelyreleased, while the spool strand of the cord is pressed against the edgeof the knife 2% and is severed.

The operation which severs the cord completes the re-engagement of theunsevered spool end of the cord between the wall of the cap 1'7 and theclamping-flange 21, so that it is firmly held thereby ready for arepetition of the process hercinbefore just described. Let it beobserved that in my machine only one strand of the cord is severed bythe knife, which is a valuable and distinctive feature of my invention,and which obviates the cutting off of a fag end of binding material thatmight clog and choke the clamper.

In passing from the position illustrated in Fig. 14 back to that shownin Fig. 11, the tied bundle is separated from the bill, and in beingseparated the knot is secured in the usual manner well understood in theart. In each succeeding revolution of the cap 17 the two sections of theouter wall of the groove 18, defined by the recesses 19, comealternately into play.

\Vhat I claim is-- 1. The combination with a rotatory knotter, of arotatory clamping-cap provided with diametrically-opposite recesses anda stationary segmental flange within the cap and upon the side nearestthe knotter, the spool end and loose end of the binding material passingfrom the knotter into the same recess and the one adjacent to theknotter and said ends passing thence around the segmental flange inopposite directions whereby the rotation of the clamper yields the looseend by retiring longitudinally upon it and takes up the slack of thespool end by forcing it around the segmental flange and whereby thenecessity for doubling'the loose end upon itself around a section of theclamper is avoided, substantially as specified.

2. In band-securing mechanism for grainbinders, the combination with arotatory knotter, of a clamping-cap provided with diametrically-opposite recesses and a stationary segmental flange withinthe cap and upon the side adjacent to the knotter, a stationary knifebetween the knotter and clamper and nearly in the same horizontal planeas the lower end of the segmental flange, the recesses in theclamping-cap being in the same vertical plane in their normal position,the bills'of the knotter springing from its upper edge in its normalposition, the loose end of the binding material being retainedunyieldingly between the segmental flange and the clamping-cap andpassing through the upper recess of the clamper to the upper side of theknotter under the bills, around the gavel, thence back under the billsof the knotter and thence to the needle, the needle end being out ofengagement with the clamper, but in a position to be engaged by saidclamper upon its rotation, and mechanism for actuating the knotter andclamper so timed that the clamper will remain stationary until theknotter has rotated a sufficient distance to accumulate binding materialfrom the needle to tie the knot and will then be rotated to pay theloose end toward the knotter and to firmly clamp and take up the slackof the needle end between the knotter and clamper by causing the upperrecess to travel toward the knotter while the beak of the knotter istraveling toward the clamper and finally releasing the loose end bypassing out of engagement with the segmental flange before the needleend is severed by the knife, substantially as specified.

3. In band-securing mechanism for grainbinders, the combination with aknotter, of a clamping-cap revolubly mounted upon a shaft to one side ofthe knotter and provided with diametrically-opposite recesses, and animmovable segmental flange within the clamper and located between theshaft of the clamper and the knotter, and a knife between the clamperand knotter, the spool end and loose end of the cord passing from theknotter through the adjacent recess in the clampingcap and around thesegmental flange between it and the clamping-cap in opposite directionswhereby the rotation of the clamping-cap takesnp the slack of the spoolend, releases the loose end and thereafter presses the spool end of thecord against the knife to sever it,-

substantially as specified.

In testimony of all which I have hereunto subscribed my name.
